I am trying to implement LCD and AMS5812 Sensor on I2C3 Bus,But AMS5812 I2C sensor is holding the I2C bus and preventing further scanning STM32F407G Discovery board. /*-[ I2C Bus Scanning ]-*/

Hi,Please find attached, Below is the schematic which i prepared for custom PCB using STM32F103C8T6 MCU. But i am unable to enter in download mode. I have tried placing same jumpers for boot mode as in Blue Pill.Only component i have omited is 32.768...
SCL / SDA on Scope. Below Observations.With AMS5812 Sensor, Peak is curved.Yellow is SDA and Violet is SCLWithout AMS5812 Sensor. I2C Scanner works fine.
Yes, only LCD works fine. also other I2C Devices like SM Pressure sensors works fine. Only problem is AMS5812 when i put on bus. No further scanning only - - - - .Core is simple I2C Discovery code. i have enabled I2C3 with 400000HZ Fast Mode.
